Rob Jones has just posted another NBA 2K11 Developer Insight. This one focusing on enhanced control.
"Many of you have been clamoring for foot-planting technology. What we realized was that we all wanted a feeling of being planted on the ground, especially when making changes of direction. The new dribbling animation system allows for that. From a control standpoint, we discussed sweeping changes to the dribbling mechanic, but in the end settled on two fundamental changes: immediate and accurate response to input as well as a command system that replicates the needed gestures to achieve a move, instead of randomly throwing sticks and/or mashing buttons. What that means is that holding multiple triggers to activate a special move is no longer necessary and that moves reflect the intention of the user. Mike Wang will go over these controls in more depth at a later stage. We wanted feathering controls, more control over when to protect the ball and when not to, and how to decide whether or not we wanted to stay faced up to the basket or not. All of these were achieved without sacrificing what you have come to expect from an NBA 2K game: Authenticity in AI and movement for every player in the league."
